The influence of herbicides on the growth and proline content of primary roots and on the ultrastructure of root caps
The root tip of a germinating seed is usually the first organ of a plant to contact possible herbicide residues in the soil. Therefore, we examined electron microscopically the responses of the root caps of very young seedlings of _Pisum sativum, Phaseolus vulgaris_ and _Vicia faba_ to low concentrations of three frequently used herbicides, chlorsulfuron, norflurazon and triallate. Additionally, herbicide-induced ... إقراء المزيد

Action of photosynthetic diuron herbicide on cell organelles and biochemical constituents of the leaves of two soybean cultivars
Two varieties of soybean (_Glycine max_ L. cv. Clark and Crawford) showed a high sensitivity to low concentrations of diuron herbicide [3-(3,4-dichlorophenyl)-1,1-dimethyl urea]. Depending on the application dose of diuron, chlorosis, necrosis, and wilting of leaves ending in death after 7 to 10 days were observed. These symptoms were more obvious in the Clark variety even at the lowest concentration ... إقراء المزيد
